PSS IIIPSS III

Brand Flowserve
Description Split, single semi-cartridge pusher seal for pumps and mixers in non-hazardous applications.
  • Applications:
    Chemical Processing, Power Generation, Chemical Transfer, Mineral Processing, Pulp and Paper
  • Industries:
    Paper Stock

The ultimate semi-cartridge split seal for pumps and mixer applications. The four piece unitized design allows for one person installation capability. All components are self contained eliminating equipment measurements small parts handling and the potential for lost parts. The improved design makes installation easy while capable of high pressure operation. The PSS III is ideally suited for pulp and paper, general chemical, wastewater treatment, municipal water, power generation and mineral and ore processing industries.

DHTW : UHTW OEM & Special Duty SealDHTW / UHTW OEM & Special Duty Seal

Brand Flowserve
Description Designed for the Power Industry, the DHTW seal has the ability to survive low or lost suction conditions for short time frames.

 

 

  • Applications:
    Boiler Feed
  • Industries:
    Water Handling and Treatment, Utilities, Boiler Circulation Systems, Crude Handling and Treatment, Crude Pipeline, Delayed Coking, Distillation, Hydrocraking, Hydrotreating, Alkylation, Logistics and Tank Farm, Water Injection, Miscellaneous Services, Products Pipeline, Boiler Feedwater Systems, SAGD, Heavy Oil and Upgrading, Catalytic Cracking, Steam Systems, Condensate Systems, Cooling Systems

Balanced, stationary multi-spring seal, designed for power industry or other high pressure/high speed applications. Using an API Plan 23 system, this seal is used in hot applications. This seal is always carefully analyzed and tuned for balance and low face deformation for critical applications. Today’s power generation plants are increasing the need for higher parameter mechanical seals for boiler feed and boiler circulating pumps. Flowserve’s DHTW has “hot standby” capability and the ability to survive low or lost suction conditions for short time frames which are important requirements in the power industry.

UHTW As DHTW, without pumping device.
